According the AP, a spokesperson for the Clintons confirmed that the baby was born on Friday.

Both Bill and Hillary Clinton have retweeted the news from their accounts, but haven't posted messages of their own yet. Now the big question: What will little Charlotte call her grandparents? Grandma and grandpa? Mimi and pop-pop? Madame President and Bill? Guess we'll have to wait until 2016—or until she can, you know, talk—to find out.

Congratulations to the Clinton and Mezvinsky families!

Update: The first photos of baby Charlotte have arrived, tweeted out by proud grandparents Bill and Hillary Clinton. We don't know whether the happy moment could get any cuter.
